Insect screen



FIG. 1 is a front elevational view of the insect screen embodying the present invention;

FIG. 2 is a side elevational view thereof;

FIG. 3 is a fragmentary perspective view thereof; and

FIG. 4 is a fragmentary sectional view thereof taken along line IV—IV in FIG. 3; and,

FIG. 5 is a fragmentary sectional view similar to FIG. 4, but in use.

The dimensions of the insect screen are indefinite. 

I claim the ornamental design for an insect screen, as shown and described.
